Honestly, every RV I've ever had has at least one spot on the floor that creaks or groans when walked over. And no, I'm not that heavy
Some of them I could fix underneath with screws. I have one in the kitchen of our current RV that I have just given up on. I just named it Harvey and learned to live with it
